Ai PARATUS FOR PRODUCING AND DEPoslTlNG FUMES'FROM QORES.

SPECIFICATON forming part of Letters Patent No. '734,844, clated July 28, 1903. y l Application filed January 2l 1902. Serial No. 90,720. (No model.)

the County of Middlesex, England, have invented certain new and useful Improvements in Apparatus forProducing and Depositing Fumes from Ores, (for which I have applied for a patent in Great Britain, dated June 27,

` p o 1901, N o. 13,115,) of which the following is a specification.

My invention relates to apparatus consist ing of furnaces for producing fumes from ores and flues for deposit of those fumes, as I shall I 5 describe, referring to the accompanying drawings. a

Figure l is a transverse section' on the line 1 1 of Fig. 2, which is a sectional plan on the line 2 2 of Fig. 1, of a set of furnaces and flues zojaccording to my invention; and Fig. 3 is a longitudinal section on the line 3 3 of Fig. 2.

I arrangeside by side'in a row a number of furnaces a, in which ores are roasted, producing fumes which are discharged by outlets b,

51 z 5 which may be provided with dampers, into a flue c. In the same structure with the fur- Iaces a and the fiue c are built in brickwork,

i i "concrete, or other suitablematerial a number i of pipes d, preferably of earthenware, con- 39 stituting flues, which open at both ends into chambers e and f, in which are formed communications from each flue to the one above ol' below it or to the one or the other side of it. i In these chambers valves or dampers,

such as that shown at g,`may be provided, so

that the fumes fromthe fine c may be directed in a zigzag course through a greater or less number of the flues to a final opening h.

Each chamber f is closed bya door k, which is hinged to a frame Z, which is built into the structure and has a projecting rib m. The door itself has in its inner face a recess holding a strip of asbestos felt or other suitable packing material facing the rib m, so that when the door is closed and pressed home by turning a fly-nut on an eye-bolt n the rib m makes, with the packing, a tight joint, preventing escape of fumes from the flues.

Each furnace has a feeding-hopper o, which is built into the structure and is provided with a conical lid p.

The fumes which are deposited in the flues d can be raked out when desired on opening the doors 70.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim Apparatus for producing and depositing fumes from ores comprising in one structure a set of furnaces,-fiues communicating therewith and with each other, passages at each end of the said flues provided with division and baffie walls, and doors and dampers or valves in the said passages, substantially as v described.

In testimony whereof I have hereunt o set nesses.
